Wet Alarm Valve



The Model AV-1-300 Alarm Check Valves are intended for use in wet pipe (automatic sprinkler) fire protection systems. They may be installed vertically or horizontally, and they are designed to automatically actuate electric and/or hydraulic alarms when there is a steady flow of water into the system that is equivalent to the discharge rate of one or more sprinklers. The valves are UL/FM approved.
